You can try your luck with congressman/senator. Even if you get them to help
you. USCIS most likely will give a standard reply reminding you that you
are within the processing time frame.
Calling USCIS is like willfully asking for humiliation. I called them about
my case status, the lady impatiently reminded me that my case is so damn new
with a Nov 2011 receipt date and it will be processed by the end of the
year.
